To study community structure I use correspondence analysis package
software. I think that CA is the best method to describe insect
community structure eventhough there have been many criticisms about
the Horseshoe Effect. To compare the results prduced by CA I would
like to use the Detrended Correspondence Analysis.
I would be grateful if someone would indicate to me how or where to
find the DCA (Hill, M.O., 1980) package software on the net.
Thanking you in advance.
